1991 polaris Indy 650 rxl EFI

This is a discussion on 1991 polaris Indy 650 rxl EFI within the Polaris forums, part of the Brand Specific Snowmobile Discussion category; 1991 polaris indy 650EFI RXL SKS My computer light flashes and my sled bogs down sometimes.
Does any one know how to check the codes ...

The ECU will display the code in the form of a blinking LED on the side of the ECU case in a coded sequence of long and short pulses.

Trouble Shooting Codes:
11. is the throttle position sensor
12. is the crankcase temp sensor
13. is the intake air temp. sensor
*14. is the atmospheric pressure sensor (rxl only)
14. is he water temp sensor
15. is the atmospheric pressure sensor
21. is the flywheel side injector
22. is the center injector (3-cyl)
22. is the Pto side injector (2-cly)
*23. is the Pto side injector (rxl)
31. is low battery voltage
32. is low charging system output
33. is CDI output

(*Note 31, 32, 33 are not used on the RXL.)
(* indicates that this codes is only used on the RXL Model)

i went out to start it and it would start it backfired a couple times as i pulled and it flashed continously one long flash and one short flash even with the key on is that a code 11 then
Thanks for your help

Also when i was trying to start it i pulled some plugs and they all were fuel soaked. It might have had a little bit of year old gas in it if that would cause any issues. Shouldn't these fuel injected sleds start better than that

Where do you get a dIMM? my ecu stopped putting out codes i bought another ecu and it didnt put out codes either. my sled wont propel itself forward and the belt doesnt slide up on the clutch at all..i can rev it out as much as i want and still doesnt move. the one spark plug is wet whats wrong do you guys know?
